Heatwave alert: Friday 18 July to Sunday 20 July 2014

Published: Friday 18 July 2014

The Met Office has issued a Heat Health Alert - Level 2, which means there is a 60 per cent chance of a heatwave occuring in London for the period between 8am on Friday 18 July to 8am Sunday 20 July 2014.

The threshold temperature for a Heatwave in London is 32°C during the day, and 18°C over night.

Dr Paul Cosford, director for health protection at Public Health England said: "While many people enjoy hot weather, high temperatures can be dangerous, especially for people who may be particularly vulnerable such as older people, young children and those with serious illnesses.

"Everyone can enjoy the sun safely by keeping out of the heat at the hottest time of the day, avoiding sunburn and staying hydrated with plenty of cool drinks. Older people and those with long-term illnesses are particularly vulnerable to the effects of very hot weather, so it’s important to look out for them and keep indoor areas as cool as possible."

Belinda Mackenzie, Lead Nurse at the trust's Hounslow Urgent Care Centre said: “While the heat wave persists, we advise members of the public to be prepared, take extra care of themselves and look out for others.

"Keep an eye on isolated, elderly, ill or very young people and make sure they are able to keep cool and if possible, check on elderly or sick neighbours, family or friends every day.

“You should also take precautions such as having plenty of cold drinks and limiting time in the heat. If you do have to go out in the heat, walk in the shade, apply sunscreen and wear a sun hat.”

She adds: "Most of us welcome hot weather and the temptation is to spend too long in the sun - however too much can cause sunburn and heatstroke."
